What happens to a star heavier than five solar masses? ... Stars about ten solar masses probably behave like our five solar mass star until they reach the end of core-helium burning. ... The Crab nebula was formed after a massive explosion ripped a star apart in 1054. ... Today, the glowing outer layers of the star are still rushing away from a tiny star in the centre. ... An incredible explosion rips through the outer layers of the star, releasing colossal amounts of energy in a supernova explosion. ...

... Astrophysics Group . ... Galaxy Formation and Evolution . ... Gas heating and outflows driven by accreting supermassive black holes (quasar phase) may affect the evolution of star formation in their host galaxy. ... The starburst galaxy M82, which expels dust and metal enriched gas out of its disk . ... The interstellar medium (ISM) plays a central role in galaxy evolution, providing the fuel for star formation and also hosting the ?fossil record? of the galaxy formation history. ...

Next: Cyg X-1 as a Up: Black Holes in Binaries Previous: Black Hole Creation in . The discovery of binary radiopulsars with massive unseen companions ( >3- ) would be of great importance to fundamental physics and modern theory of stellar evolution, providing a compelling evidence for the existence of BH in nature. The formation of binaries consisting of a BH in a pair with a radiopulsar (PSR) has been discussed previously by Narayan et al. ... Здесь должна быть Table 11 (Note к Table 11) . ...

... General information . ... Staff . Research staff . ... Information . ... Historical highlights . Historical research . ... This process is thought to occur in circumstellar disks of gas and dust around young stars on rather short timescales : infrared surveys show that the number of low mass stars with disks drops dramatically for stars older than 10 Myr, suggesting that in order to form large solids before the disk disperses, the growth process has to take place within a few million years. ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...
